This article describes supramolecular FeO/SiO decorated trimesic acid-melamine (FeO/SiO-TMA-Me) nanocomposite that can be prepared with features that combine properties of different materials to fabricate a structurally unique hybrid material. In particular, we have focused on design, synthesis and evaluation a heterogeneous magnetic organocatalyst containing acidic functional-groups for the synthesis of biologically important imidazole derivatives in good to excellent yields. The introduced FeO/SiO-TMA-Me nanomaterial was characterized by different techniques such as FTIR, XRD, EDX, FESEM, TEM, TGA and DTA. As a noteworthy point, the magnetic catalytic system can be recycled and reused for more than seven consecutive runs while its high catalytic activity remains under the optimized conditions.
本文描述了超分子 FeO/SiO 修饰的均苯三甲酸-三聚氰胺（FeO/SiO-TMA-Me）纳米复合材料，该复合材料可以将不同材料的特性结合起来，制备出具有独特结构的杂化材料。特别是，我们专注于设计、合成和评价一种含有酸性功能基团的非均相磁性有机催化剂，用于在优化条件下以良好至优异的收率合成具有重要生物学意义的咪唑衍生物。所引入的 FeO/SiO-TMA-Me 纳米材料通过不同的技术进行了表征，如 FTIR、XRD、EDX、FESEM、TEM、TGA 和 DTA。值得注意的是，在优化条件下，磁性催化体系可以在超过七个连续的循环中回收和重复使用，而其高催化活性仍然保持不变。
